| bacteriophage t4 | <microbiology> A bacteriophage (a virus which infects bacteria) which uses DNA as its genetic material (some viruses use RNA) and is unusually large. (09 Oct 1997) |
|---|---|
| bacteriophage t7 | <microbiology> A bacteriophage (a virus which infects bacteria) that is useful to geneticists because it has a very strong promoter region which strongly encourages transcription of its gene by specific T7 RNA polymerase. Geneticists can take the part with the promoter and attach their own genes of interest to it so that they can control transcription rates of their gene by choosing the amount of the RNA polymerase to put in. (09 Oct 1997) |
| bacteriophage T7 induced DNA polymerase | <enzyme> Complex of two proteins, phage gene 5 protein and E coli thioredoxin Registry number: EC 2.7.7.- Synonym: t7 phage DNA polymerase, sequenase, t7 DNA polymerase, thermo sequenase (26 Jun 1999) |
| bacteriophage typing | A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages. (12 Dec 1998) |
| bacteriophages | Viruses whose host is a bacterial cell. (12 Dec 1998) |
| bacteriophagia | The lysis of bacteria by bacteriophage. Synonym: bacteriophagia, d'Herelle phenomenon, Twort phenomenon. (05 Mar 2000) |
| bacteriophagology | The study of bacteriophages. Synonym: protobiology. (05 Mar 2000) |
| bacteriopheophorbide | Bacteriophorbin with the side chains found in bacteriochlorophyll, but lacking the phytyl group. (05 Mar 2000) |
| bacteriopheophorbin | De-esterfied bacteriopheophorbide, derived from bacteriochlorin. (05 Mar 2000) |
| bacteriopheophytin | Bacteriopheophor bide with a phytyl ester on the C-17 propionic residue; bacteriochlorophyll less its magnesium residue. (05 Mar 2000) |
| bacteriophorbin | Phorbin further saturated by addition of two hydrogens to C-7 and C-8. (05 Mar 2000) |
| bacteriophytoma | <microbiology, oncology> A lesion resembling a tumour that is caused by bacteria. (09 Oct 1997) |
| bacterioprotein | One of the albuminous substances, or proteins, within the cells of bacteria; these substances vary in their character and properties. (05 Mar 2000) |
| bacteriopsonin | An opsonin acting upon bacteria, as distinguished from a haemopsonin which affects red blood corpuscles. (05 Mar 2000) |
| bacteriorhodopsin | <microbiology> A light driven proton pumping protein (248 residues, 26 kD), similar to rhodopsin, found in purple patches in the cytoplasmic membrane of the bacterium Halobacterium halobium. It is composed of 7 transmembrane helices and contains the light absorbing chromophore, retinal. Light absorption maxima: 568 nm (light adapted), 558 nm (dark adapted). Each photon results in the movement of 2 protons from cytoplasmic to extracellular sides of the membrane. The resulting proton gradient is used (amongst other things) to drive chemiosmotic synthesis of ATP. (18 Nov 1997) |
